Julien's Auctions staged the sale at the Hard Rock Cafe in Manhattan, where the guitar fetched far more than its original pre-auction estimate of between 200,000 and 300,000.

The sale was a "once-in-a-lifetime opportunity to own one of the rarest pieces of Beatles memorabilia ever to be offered," the auction house said.

The guitar was previously on display at a museum in Ireland and was sold a few years ago by Christie's Auction House for more than $100,000.
